Display Data Only
Measurement channel: 2, computation channel: none
Data Max data no. and sampling length
Display data Max data no. = 1,200,000/(2 CH × 4 bytes + 0 × 8 bytes) = 150,000. However,
since 100,000 data points is the limit,
Max data no. = 100,000
When the display update rate is 30 min/div (60 s sampling interval)
Sampling length = 100,000 data points × 60 s = 6,000,000 s (approx. 69 days)
Measurement channel: 12, computation channel: 6
Data Max data no. and sampling length
Display data Max data no. = 1,200,000/(12 CH × 4 bytes + 6 × 8 bytes) = 12,500
When the display update rate is 30 min/div (60 s sampling interval)
Sampling length = 12,500 data points × 60 s = 750,000 s (approx. 8 days)
Event Data Only
Measurement channel: 2, computation channel: None
Data Max data no. and sampling length
Display data Max data no. = 1,200,000/(2 CH × 2 bytes + 0 × 4 bytes) = 300,000
However, since 120,000 data points is the limit,
Max data no. = 120,000
When the event data sampling interval is 1 s
Sampling length = 120,000 data points × 1 s = 120,000 s (approx. 33 hours)
Measurement channel: 12, computation channel: 6
Data Max data no. and sampling length
Event data Max data no. = 1,200,000/(12 CH × 2 bytes + 6 × 4 bytes) = 25,000
When the event data sampling interval is 1 s
Sampling length = 25,000 data points × 1 s = 25,000 s (approx. 7 hours)
Display Data and Event Data
Measurement channel: 2, computation channel: none
Data Max data no. and sampling length
Display data Maximum number of data points = 900,000/(2 CH × 4 bytes + 0 × 8 bytes) =
112,500
However, since 75,000 data points is the limit,
Max data no. = 75,000
When the display update rate is 30 min/div (60 s sampling interval)
Sampling length = 75,000 data points × 60 s = 4,500,000 s (approx. 52 days)
Event data Max data no. = 300,000/(2 CH × 2 bytes + 0 × 4 bytes) = 75,000
However, since 30,000 data points is the limit,
Max data no. = 30,000 data points
When the event data sampling interval is 1 s
Sampling length = 30,000 data points × 1 s = 30,000 s (approx. 8 hours)
Measurement channel: 12, computation channel: 6
Data Max data no. and sampling length
Display data Max data no. = 900,000/(12 CH × 4 bytes + 6 × 8 bytes) = 9,375
When the display update rate is 30 min/div (60 s sampling interval)
Sampling length = 9,375 data points × 60 s = 562,500 s (approx. 6.5 days)
Event data Max data no. = 300,000/(12 CH × 2 bytes + 6 × 4 bytes) = 6,250
When the event data sampling interval is 1 s
Sampling length = 6,250 data points × 1 s = 6,250 s (approx. 1.7 hours)
